part 1: unwanted transmigration into a shitty novel as the Scum Villain.

Lan Shen dies while eating a meat bun reading a trashy novel then something unexpectant happens, he is transmigrated into the same trashy novel he was reading and worse, not the main character or at least a minor role, BUT THE VILLAIN LAN JINGYI!!! who was killed by the Protagonist Lan Sizhui (indirectly) and now he has some know it all bitchy system. will he prevent his painful demise? or is it inevitable?...
